Abstract
Patient: A 43-year-old male patient complained of articulation disorders after the placement of an adhesion bridge to restore maxillary anterior missing teeth. Since severe bone resorption was detected by X-ray CT in the edentulous region, implant prosthetic treatment was performed following autogenous bone grafting. Finally, the edentulous space was restored with an implant-supported fixed prosthesis.
Discussion: Symmetry of the oral cavity proper, consisting of alveolar ridge form and palatal wall of the dental arch, is closely related to articulation function, therefore abnormalities of anterior palatal form can cause articulation disorders. In this case, the palatal wall of the superstructure was fabricated to be as symmetrical as possible, taking tongue function into consideration. Since the superstructure was fixed with cementation, improvement of articulation and comfort of the tongue were obtained.
Conclusion: Improvement of articulation was achieved by symmetrical restoration of the oral cavity proper.
